Power two independent flashes at the same time with the Bolt PP-500DR Dual-Outlet Power Pack with Two PP-5800BP Removable Batteries and PP-MCX Mounting Clamp Kit from B&H. With one power pack and two battery packs, you will get twice the lasting power for any event, and the mounting clamp lets you conveniently hang the whole battery unit on a bar or light stand while shooting.
The PP-500DR Dual-Outlet Power Pack with Removable Battery from Bolt is an interchangeable battery system that is compatible with most on-camera flashes such as Nikon, Canon, Sony, Bolt, Sunpak, Vivitar, Metz, and other popular flashes. The dual outlets on the pack enable you to use two on-camera flashes at the same time, and the outlets have locking connectors to secure the power cables and prevent them from falling out. The portable lithium-ion battery is rechargeable via the included AC adapter, which takes approximately 4.5 hours to fully charge.
At full capacity, the battery supplies up to 2700 flashes at full power while you keep watch of the battery's life through the meter display. The battery recycles between flashes as fast as one second, so you never miss a shot. A 1A USB charging port is supplied to charge other small electronic devices like a smartphone. A belt clip and shoulder strap are also included, which gives you plenty of carrying options.
The Bolt PP-5800BP Cyclone 5800mAh Battery Pack is a rechargeable lithium-ion battery that is compatible with the PP-400DR and PP-500DR Power Packs. The battery has an output power of 11.1V and a capacity of 5800mAh, which provides up to 2700 full-power flashes. A power indicator keeps track of remaining power, but the battery is rechargeable at any time during use because it doesn't have a memory effect. The battery is compact enough to be portable and interchangeable, so you're never without power. The integrated USB port delivers 5V of output power and can be used as a stand-alone charger for a smartphone or tablet without being connected to a Cyclone Power Pack.
Easily mount your power pack to a light stand or attach a multitude of other items where you need them by using the versatile PP-MCX Mounting Clamp from Bolt. The clamp opens from 0.1-1.8" for use on light stands, tables, desks, doors, and other flat surfaces and it features a belt clip slot that allows users to easily hang their power pack. On the back two 1/4"-20 threads at different angles and one 3/8"-16 thread are available for mounting lights and other accessories. To prevent damage, the clamp features a rubber coating and it has the ability to hold up to 2 lb of gear when attached to a light stand or 8 lb on a flat base.
